Door surface assembly method having watertight performance and obtained watertight door

Abstract

The invention provides a door surface assembly method having watertight performance and an obtained watertight door. The door surface assembly method comprises the steps of assembling a door front surface sealing plate, a grating plate and a door back surface sealing plate to form a door plate, wherein the grating plate is arranged between the door front surface sealing plate and the door back surface sealing plate, the size of the door back surface sealing plate is larger than that of the door front surface sealing plate, the distance between an outer edge of the door back surface sealing plate and an outer edge of the corresponding door front surface sealing plate is 25-30 millimeters, a rubber sealing strip is arranged at an edge of the grating plate so that an outer edge of the rubbersealing strip exceeds out of an outer edge of the door back surface sealing plate by 5-10 millimeters, and the rubber sealing strip is a sealing strip in which a cavity is formed. The invention also proposes application of the watertight door. According to the watertight door assembly method proposed by the invention, the watertight door has excellent watertight performance by a special design ofa sealing structure, and the watertight door is long in service lifetime and low in maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a method for assembling a door on a ship or a submarine, and the obtained watertight door. Background technique [0002] The watertight door on the ship is arranged in the confined space of the ship or the entrance and exit position of the sealed space. All watertight doors on board the ship should be kept closed during the voyage, and when they must be opened during the voyage due to work needs, they should be closed at any time. Watertight doors have extremely high requirements for operational flexibility. Conventions and regulations require that any watertight door operating device, whether powered or not, must be able to close the watertight door when the ship is heeling at 15°. On the other hand, watertight doors on ships require extremely high watertight performance to prevent the hull from being flooded in the event of a rupture, and to ensure that the doors on ...

Problems solved by technology

This design makes the operation of opening and closing the door laborious, and the material of the door is generally metal, such as A-36 low-carbon steel; multiple times of forceful opening and closing of the door will easily lead to stress cracking, which will cause great loss to the door and shorten the life of the door

In the existing technology, in order to prevent water from leaking into the engine room, there are also technologies for designing additional components such as card slots (such as the utility model patent CN205311837U), which leads to an increase in assembly costs and an increase in the total weight of the hull
